Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to human waste treatment for treating human waste outdoors, where there is no purification treatment facility, transportation such as ships and trains, and tunnels that are closed from the surroundings and do not allow vacuum cars to enter. More particularly, the present invention relates to a catalyst cleaning mechanism of a human waste treatment apparatus capable of removing dust from a catalyst for reducing odor.

[0002]

2. Description of the Related Art In a general house, human waste excreted from the human body is generally discharged to a sewer pipe by a flush toilet or the like, or temporarily stored in a septic tank for purification and then discharged to a river. However, when performing outdoors, for example, in a venue where a large number of personnel such as an athletic meet, a trade fair, and a rally are held, a temporary toilet is conventionally provided to eliminate the physiological phenomenon of the participants.

[0003] As described above, in the disposal of human waste outdoors or in a place where there is no purification facility, a movable temporary toilet is conventionally used. However, most of them have a structure having a toilet tank for temporarily storing human waste, and human waste excreted from the human body is directly stored in this toilet tank. Therefore, after using the temporary toilet, the human waste stored in the toilet tank must be collected by a vacuum car or the like and transferred to a human waste processing facility. For this reason, the post-collection processing is required, and the post-processing is troublesome and unsanitary.

[0004] Transportation systems such as trains, buses, ships, and the like that travel long distances are provided with a dedicated tank for storing excreted human waste. After the processing, a method of collecting by a vacuum car at a terminal station or a relay point was generally used.

[0005] As described above, in the conventional disposal of toilets or movable transportation, human waste is mostly stored while being excreted from the human body and then collected. For this reason, any of the storage method, the recovery method, and the treatment method has to be said to be non-modern and extremely unsanitary. Therefore, when the temporary toilet has been used for a long period of time, excreted human waste remains in the tank, causing odor. In addition, since the operation of cleaning the temporary toilet after use is disliked by workers, it is not preferable from the viewpoint of modernization of maintenance of the temporary toilet and the toilet of transportation.

Under such circumstances, various methods for sanitary disposal of human waste have conventionally been considered. For example, there is a method of disinfecting and deodorizing by inputting a chemical agent together with human waste. This method is often used for transportation such as the Shinkansen, but since urine containing chemicals circulates between the tank and the toilet, the water flowing through the toilet becomes dirty after a long-term use.
It had a bad smell and was unpopular for users. Further, in order to empty the tank and prepare it for the next use, a large amount of chemical must be introduced into the tank, which has the disadvantage of increasing the cost of the chemical.

[0007] Further, a method has been considered in which human waste is stored in a bag of vinyl or the like and packed to prevent the emission of odor. However, it is necessary to use a plastic bag having a considerably large area for one excretion, which increases the processing cost and requires a treatment for separating human waste from the plastic bag at a later date. With this method, the process until packing is relatively easy,
Subsequent processing is cumbersome, and the processing facility becomes large.

Further, a method has been considered in which excreted human waste is stored in a closed evaporation container, and the human waste is directly heated and evaporated by the heat of a burner. For example, patent publication Showa 4
No. 17236, Patent publication No. 2545, Showa 1974, Patent publication No. 3149, Showa 50, Patent publication 58
No. 239, Japanese Patent Publication No. 110268/1982, and Japanese Patent Publication No. 55415/165415 are known. However, in these methods, since the flame of the burner is squirted into human waste to evaporate from the surface,
Moisture, a major component of human waste, cannot be evaporated efficiently,
It required a lot of energy to completely process human waste.

[0009] Further, with these configurations, the evaporating container is not cleaned after the human waste is dried, and the residue that cannot be evaporated from the human waste accumulates on the bottom of the evaporating container in a long-term use. The thermal efficiency became worse. In such a case, in order to clean the residue, the apparatus must be disassembled and maintenance must be performed each time, and there is a disadvantage that the maintenance is troublesome and expensive.

As described above, there are many problems in the treatment of human waste in a temporary toilet, and it is difficult to completely excrete human waste in the temporary toilet. Due to such social demands, the same inventor as the applicant of the present invention has proposed a human waste processing apparatus capable of evaporating water, which is a major component of human waste, by heating the human waste. The proposed human waste processing apparatus is provided for use in a temporary toilet, and a sealed drying pot (heat-resistant evaporating vessel) for storing human waste is provided in the apparatus. A rotatable stirring blade is rotatably supported, and the drying pot has a configuration in which a plurality of heat storage elements that roll on the inner bottom together with human waste in accordance with the rotation of the stirring blade are housed.

[0011] Then, the drying pot is heated from the outside to heat the waste in the drying pot, and at the same time, by rotating the stirring blade, the waste can be mixed and the moisture of the waste can be quickly evaporated. At the time of this evaporation, the spherical heat storage element rolls at the bottom of the drying kettle to uniformly heat the temperature of the human waste, and to transfer the heat of itself to the human waste to increase the heating rate. (For example, Japanese Patent Application No.
No. 4150).

This mechanism is basic, and the inventor has successively proposed an improved human waste treatment apparatus. Japanese Patent Application No. 164594/1990 discloses a configuration in which a pipe for supplying air to a drying pot and an exhaust pipe are connected, and the exhaust pipe is connected to a dust collector and a condenser. In this mechanism, the water vapor of the human waste evaporated inside the drying pot is condensed and collected, and can be circulated and used for washing water.
Dust remaining in the drying pot after drying of human waste is sucked and collected together with the air, and the dust can be separated from the air by a dust collector. With this mechanism, moisture can be collected from the human waste put into the drying pot, and the non-evaporable dust remaining in the drying pot after drying the human waste can be cleaned, so that the human waste processing apparatus can be used continuously. It is.

In Japanese Patent Application No. 411577/1990, a human waste treatment apparatus is unitized so as to be easily installed in a temporary toilet. In this mechanism, the structure of the drying pot is formed in a cylindrical shape so that human waste can be introduced from the side of the drying pot. For this reason, there is no need to dispose the toilet on the upper part of the drying pot, and the height of the apparatus can be reduced.

In Japanese Patent Application No. 412559/1990, a storage tank for storing urine collected by a urinal is provided, and the storage tank and the urinal are connected by an ejection pipe. In this configuration, urine and urine are excreted in the urinal, and urine is separated so as to be collected in the urinal. It can be put into a drying pot. For this reason, the toilet can be cleaned with urine, and the temporary toilet can be flushed even in a place where water supply cannot be installed.

[0015] Further, in Japanese Patent Application No. 03-67538,
A mechanism is shown in which a liquid level sensor is inserted from the side of the drying pot, and the position of the liquid level of the human waste put into the drying pot can always be detected. In this mechanism, by detecting and judging the liquid level of the human waste, it is possible to prevent a large amount of human waste from being temporarily supplied, thereby preventing the ability of the human waste to evaporate, and to prevent a failure due to overflow. This can prevent the occurrence.

In Japanese Patent Application No. 189280/1991,
A reheating box with a built-in heater is arranged between the blower and the catalyst box, and a bypass is provided between the catalyst box and a pipe connecting the drying pot and the dust collector. With this configuration, the air from the drying pot can be made to flow to the catalyst box by the bypass during the evaporating process of the excrement, and the air flow can be made more efficient. Further, during the cleaning process of the drying pot, the bypass is closed, and the air containing dust can flow to the dust collector as it is.

Japanese Patent Application No. 189281/1991 is an improvement of the Japanese Patent Application No. 189280/1991. A bypass pipe is connected to a pipe connecting the drying pot and the dust collector, and the end of the bypass pipe is connected to the end of the bypass pipe. Is a configuration in which the negative pressure side of the ejector is connected and the catalyst box is connected to the ejector. In this configuration, when the bypass pipe is open, the air in the drying pot is forcibly sucked by the ejector and made to flow into the catalyst box, so that the air flow efficiency of the drying pot is increased and the evaporation is promoted. effective.

In Japanese Patent Application No. 265237/1991, a trash collection box is connected to an exhaust pipe of a drying pot, and a trash bag formed of paper, cloth, or the like is stored in the trash collection box. In this configuration, when cleaning the drying pot, air containing dust is caused to flow into the trash bag, and only dust passes through the trash bag and the dust can be separated. There is an effect that dust can be separated more reliably than a cyclone type dust collector.

[0019] In Japanese Patent Application No. 051170/1993,
The toilet and the human waste treatment device are separated, and the human waste put into the toilet can be stored in a tank and then subjected to a badge-type continuous evaporation / drying process. In this human waste processing apparatus, an opening for introducing human waste is formed at the top of a slightly spherical drying pot that can be rotated on a horizontal axis, and a spherical heat storage body is stored inside the drying pot. This is a configuration in which a burner capable of heating is provided. With this configuration, the human waste put into the drying pot is evaporated and dried by the heat of the burner. During this process, the human waste can be stirred by the heat storage body by swinging the drying pot, and after drying, the drying pot is rotated. This allows dust to fall from the opening.

In Japanese Patent Application No. 121968/1993, a switching valve is interposed between the blowing pipe and the exhaust pipe of the drying kettle, and the dust collection box and the blower can be connected in series to the drying kettle via the switching valve. is there. With this configuration, air is circulated inside the waste disposal apparatus when cleaning the drying pot, and there is an effect that dust collection efficiency is improved.

Japanese Patent Application No. 125360/1993 has a configuration in which a high-frequency coil is installed on the lower surface of a drying pot, and high-frequency power is supplied to the high-frequency coil to generate electromagnetic waves. Since high-frequency electromagnetic waves are mixed in the drying pot, the drying pot itself generates heat instead of direct heating, thereby heating the human waste. For this reason, it is possible to quickly heat only the necessary drying pot, which has an effect of reducing heat loss.

In Japanese Patent Application No. 307135/1993, the drying pot itself is normally upright, the upper part of the drying pot is always open, and the drying pot can be turned over only during cleaning. A heat storage body is accommodated inside the drying pot, and a lid plate that can be closed at the time of a fall is provided at an upper opening. In this configuration,
During the process of evaporating and drying the excrement thrown into the drying oven, the drying oven itself stands still and stands upright. The dust remaining in the opening can be released from the opening. At the time of this dust emission, the lid plate (there are several small holes on its surface) automatically closes the opening of the drying pot,
It prevents the heat storage material from dropping, and allows only dust to be released to the trash dish through a small hole in the lid plate.
The configuration of the human waste treatment apparatus can be simplified.

Further, in Japanese Patent Application No. Hei 5-314445,
The drying pot is supported rotatably, the output of the motor is engaged with the outer periphery of the drying pot, and a plurality of spherical heat storage elements are stored in the drying pot. Three baffle plates are inserted from the lid plate to the inside of the drying pot. In this configuration, unlike the drying pot of the conventional human waste processing apparatus, the drying pot itself rotates about a vertical axis, and the human waste can be heated by the electromagnetic waves from the high-frequency coil. The heat storage element accommodated in the drying pot does not rotate with the drying pot due to the baffle plate, but rolls at the bottom of the drying pot, and can stir and heat human waste. In this configuration, there is no need to rotate the stirring blade inside the drying pot,
The height of the entire human waste processing apparatus can be reduced. Further, in the configuration in which the rotating blades are rotated, an excellent effect that foreign matter other than human waste (for example, a ballpoint pen, clothing, a clock, etc.) put into the drying pot can be eliminated due to entanglement with the rotating rotating blades. It has.

Also, in Japanese Patent Application No. 151631/1994, similarly, a drying pot is rotatably supported, the output of the motor is meshed with the outer periphery of the drying pot, and a spherical , And a single baffle plate is inserted from the lid plate located at the upper part of the drying pot toward the inside of the drying pot. Even with this configuration, the drying pot itself rotates around a vertical axis, and the human waste can be heated by the electromagnetic waves from the high-frequency coil. According to the present invention, the baffle plate is formed of one piece fixed to the suction pipe, and since the heat storage body does not fit between the plurality of baffle plates, the heat storage body can be reliably rolled by rotation of the drying oven. Met.

In these newly proposed human waste processing apparatuses, the excreted human waste can be heated while being sealed in the drying pot, and the human waste can be mixed by rotating the stirring blades and the drying pot. . The temperature of the heated human waste uniformly rises, and most of the moisture, which is a component, evaporates and is released into the atmosphere as water vapor. By this heating and mixing, the evaporation rate of the human waste is increased, and the processing time of the human waste can be shortened. In addition, water vapor diffused into the atmosphere is deodorized with a catalyst or the like. This is also preferable from the viewpoint of the above.

It is extremely sanitary to evaporate and diffuse human waste in the sealed evaporating container in this manner, and the operation can be systematized, so that no burden is imposed on the operator in maintenance and the like. is there. However, most of the conventional human waste processing apparatuses have a configuration in which a drying pot is fixed, and the stirring blades are rotated inside the drying pot to mix the human waste. In this mechanism, when foreign matter other than human waste, which cannot be evaporated, is introduced into the drying pot, the rotating stirring blade meshes with the foreign matter, which often causes a failure. For example, a metal ballpoint pen, belt, clothing, or the like may be thrown into the toilet bowl due to the carelessness of the user. When these foreign substances are introduced into the drying pot, the foreign substances bite between the stirring blade and the drying pot, causing rotation of the stirring blades to stop or causing the stirring blades and the drying pot to wear.

Further, if the stirring blades are stored inside the drying pot, the limited internal space of the drying pot is narrowed by these mechanisms, so that the internal space of the drying pot cannot be used effectively. Had become.

To solve such a disadvantage, Japanese Patent Application No.
In Japanese Patent Application No. 314445 and Japanese Patent Application No. 151631, Japanese Patent Application Laid-Open No. HEI 15-1631 discloses a configuration in which the drying pot itself is rotated so that human waste can be mixed without using a stirring blade. But
In this mechanism, the drying pot must be rotatably supported, and further, the drying pot must not be moved in the vertical direction, and must be supported so that the central axis is not deviated. If the rotating drying kettle moves up and down or if the rotating shaft moves in a miso grinding motion, the opening end of the drying kettle will be separated from the lid plate, and the airtightness of the drying kettle will not be maintained.

As described above, in order to restrict the rotational movement of the drying oven, a regulating mechanism (a roller or the like) in two directions, a vertical direction and a rotating direction, is required, and this regulating mechanism must be complicated. It is. In addition, if the regulation mechanism becomes complicated, it takes time and effort to assemble the drying pot, and it takes time to remove the drying pot for inspection and maintenance of the human waste processing apparatus. .

Dust remaining after the human waste is evaporated and dried in the drying oven must be removed in order to continuously treat the human waste, but a suction pipe for cleaning is attached to the drying oven by a predetermined amount. It was difficult to control the insertion by the length. Conventionally, the amount of movement of the suction pipe is detected and controlled so that the suction pipe can be moved up and down by an appropriate length. However, a mechanism for moving the suction pipe and a control mechanism are complicated.

For this reason, the inventor of the present application filed Japanese Patent Application No.
No. 9457 has filed an application for a human waste treatment apparatus in which these disadvantages are improved. In this newly proposed human waste processing apparatus, a rotation holding means is provided at the upper part of the gantry, an evaporation container is hung below the rotation holding means, and an electromagnetic heating means is provided at an interval on the lower surface of the evaporation container. It is characterized by the following. In this proposed configuration, since the evaporating container is suspended and rotated, there is no need to provide any support means on the lower part and the side surface, and the mechanism for holding the evaporating container is extremely simple. Also, in this configuration,
Only the evaporation container can be removed from the lower part of the rotation holding means, and it becomes easy to expose the inside of the evaporation container to the outside for periodic inspection and maintenance.

[0032]

When the human waste is evaporated and dried in this way, ammonia,
It contains malodorous components such as urea, and spreads malodorous to the surroundings as it is. For this reason, in any of the conventional human waste treatment apparatuses, a catalyst that oxidizes and reduces a malodorous component and transforms it into an odorless state is usually disposed in a flow path of the air. Since water vapor and air flow into the catalyst body while the human waste evaporates, impurities such as fibrous substances contained in the human waste adhere to the surface of the catalyst particles constituting the catalytic body. If such impurities remain attached, the air and the catalyst particles do not come into contact with each other, and the malodorous components that should be oxidized and reduced are not odorlessly transformed by the catalyst particles, thereby deteriorating the function of the human waste processing apparatus. is what happened.

For this reason, it has been necessary to periodically clean the catalyst body even when using the human waste treatment apparatus.
The applicant of the present application has developed a mechanism in which the direction of the air flow flowing through the catalyst body is reversed, and by the flow of air flowing back through the catalyst body, impurities attached to the surface of the catalyst particles are blown off and automatically cleaned. (Japanese Patent Application No. 211989 No. 8). However, in this mechanism, only clean air flows from the direction opposite to the direction of water vapor evaporating from human waste. For this reason, it is possible to remove dust that is lightly attached to the surface of the catalyst particles, but it is possible for dust in a wet state to adhere to the surface of the catalyst particles and then be dried and solidified. At the time, it was difficult to remove them with the flow of air. In the cleaning of dust by such an air flow, dust on the surface of catalyst particles cannot be completely removed, and the function of oxidizing and reducing the catalyst body has been reduced in the long term. For this reason, there has been an urgent need to develop a mechanism that can automatically clean the catalyst body to which dust has adhered.

The contact surfaces of the stirring plate 104, the mounting plates 100 and 101, and the side plates 102 and 103 are hermetically fixed by electric welding or the like. Further, an upper end of a skirt plate 105 formed by bending a thin steel plate into a tapered shape is fixed to a semicircular lower end of the stirring plate 104.
The skirt plate 105 is assembled in a shape similar to a bulldozer discharge plate. As shown in FIG. 6, the stirring plate 104 has a curved surface ratio set to be larger than the curved surface ratio inside the drying pot 41, and the length of both ends of the stirring plate 104 is slightly smaller than the inner diameter of the drying pot 41. It is set to the extent that it will be. The straight line connecting both ends of the stirring plate 104 passes near the center of the drying pot 41 as shown in FIG. 6, and the bottom of the drying pot 41 is divided into two by the stirring plate 104 and the skirt plate 105.

The user must be set in a standby state so that human waste excreted in the toilet bowl 16 can be immediately processed.
The setting of the temporary toilet 11 in the “standby” state is started when the administrator of the temporary toilet 11 or the person in charge of the event hall turns on the power switch 192 (turns on the power). When the power switch 192 is turned on,
The excrement processing apparatus 15 starts operating, and is ready to start processing excreted excrement at any time. Power switch 19
The central processing circuit 191 switches to a state in which the motor control circuit 201, the on-off valve control circuit 202, and the heater control circuit 203 can be operated by the ON signal from the second control signal.

<Use of temporary toilet 11 by user>

As described above, when the power switch 192 is turned on, each mechanism of the human waste processing apparatus 15 is in a standby state,
The user can use the temporary toilet 11 at any time. To use the temporary toilet 11 on standby, the user opens the door 14 to enter the interior of the house 13 and excretes human waste toward the toilet 16. The excreted human waste is received by the toilet bowl 16 and temporarily stored here.

<< Injection of human waste into drying pot 41 >>

[0153] The user using the toilet 16 of the temporary toilet 11 in this way, after the defecation is completed, the house 13
By pressing the processing switch 183 provided therein, the human waste of the toilet bowl 16 is put into the drying pot 41, and the drying process is started. When the processing switch 183 is pressed, the central processing circuit 191 opens an open / close valve (not shown), opens the lower part of the toilet bowl 16, and allows the human waste to flow downward. Then, the excrement falls down the joint 80 and moves to the introduction pipe 79, flows through the oblique inside of the introduction pipe 79, and flows into the drying pot 4.
Entered into 1. In addition, a part of human waste is joint 80,
Although it adheres to the inner wall of the introduction pipe 79, a small amount of washing water is sprayed on the toilet 16 when it is put into the drying pot 41, and the excrement adhered to the drying pot 41 is washed together with the washing water into the drying pot 41. It can also flow in. Toilet bowl 1 for a predetermined time
When the on-off valve of No. 6 is opened and the washing water is injected, the central processing circuit 191 determines that all the human waste has been introduced, and closes the on-off valve.

<< Restriction on Use of Temporary Toilet 11 >>

[0155] When the human waste is put into the drying pot 41, the user uses the temporary toilet 11 to switch the processing switch 18
It is performed every time 3 is pressed. However, if the human waste is continuously supplied, the human waste is eventually supplied exceeding the capacity of the drying pot 41, and the next evaporation / drying process cannot be performed. For this reason, when the amount of human waste put into the drying pot 41 reaches a predetermined amount, the use of the temporary toilet 11 is stopped, and the use by the user is restricted.

That is, when the liquid level of the human waste put into the drying pot 41 rises and finally exceeds the amount that the human waste can be stored inside the drying pot 41, the liquid level of the human waste comes into contact with the liquid level sensor 181. Therefore, the electrodes of the liquid level sensor 181 are short-circuited. Then, this signal is transmitted to the overflow determination circuit 195, and the overflow determination circuit 1
95 informs the central processing circuit 191 that the human waste has been introduced into the drying pot 41 to the limit of its processing capacity. Then, the central processing circuit 191 makes a determination to temporarily restrict the use of the temporary toilet 11 and outputs a determination signal to the use stop display circuit 193.

Then, the use stop display circuit 193 turns on the display lamp 194 provided inside the temporary toilet 11, notifies the user that the drying pot 41 of the temporary toilet 11 has overflown, and turns off the display lamp 194. You will be warned not to use it until you do. At the same time, the central processing circuit 191 does not operate the opening / closing valve of the toilet 16, so that even if the user excretes excrement into the toilet 16, it restricts the excrement into the drying pot 41 no more. By this operation, the evaporating and drying process is performed smoothly by preventing the excrement of the processing capacity from being thrown into the drying pot 41. The operation of restricting the use of the temporary toilet 11 is as follows. After the liquid level of the human waste comes into contact with the liquid level sensor 181, a series of human waste processing cycles described below is completed.
Until all human waste has been evaporated. .

<Start of human waste evaporation / drying process>

As described above, when the processing switch 183 is pressed by the user and the excreted excrement is put into the drying pot 41, the central processing circuit 191 closes the opening / closing valve of the toilet bowl 16, and then the drying operation is performed. Evaporation of human waste stored in the kettle 41
Start the drying process. In this processing, the central processing circuit 1
In accordance with steps stored internally in advance 91, individual control signals are transmitted to the motor control circuit 201, the on-off valve control circuit 202, and the heater control circuit 203 to instruct the evaporation and drying processes. When the evaporation / drying process is started, the on-off valve 124 shown in FIG. 18 is open, the on-off valve 171 is closed, and the switching valve 161 connects the air pipe 150 and the air supply pipe 162. It is in a state of communication.

In this evaporating / drying process, <heating of the drying pot 41>, <reheating by the reheating heater 134>, <cooling of the cooling box 129>, and <air in the drying pot 41 by the exhaust unit 25> A series of operations of <discharge>, <rotational movement of the stirring unit 28>, and <stirring of human waste by the heat storage unit 50> are performed. Each operation will be sequentially described below.

<< Heating of Drying Kettle 41 >>

When a control signal is input from the central processing circuit 191 to the heater control circuit 203, the heater control circuit 20
Numeral 3 supplies power to the reheater 134 and the high-frequency generation circuit 204, and the high-frequency generation circuit 204 supplies high-frequency power to the high-frequency coil 118. When high-frequency power is supplied to the high-frequency coil 118 housed in the coil container 119, the high-frequency coil 118 generates an electromagnetic wave in a vertical direction, and the high-frequency electromagnetic wave leaks out of the coil container 119 and is stirred at a high frequency. I do. The high-frequency electromagnetic waves leaking from the coil container 119 pass through the bottom of the drying pot 41 approaching the upper surface of the coil container 119, and the electromagnetic waves
1 will be mixed at the bottom.

For this reason, the phenomenon of electromagnetic induction heating occurs due to the mixing of high frequency electromagnetic waves at the bottom of the drying pot 41 (the drying pot 41 is made of a metal material such as iron). The drying pot 41 itself generates heat. At the same time, this electromagnetic wave also mixes with the heat storage body 50 stored in the drying pot 41, and the heat storage body 50 itself also generates heat. Since the drying pot 41 and the heat storage unit 50 generate heat due to the electromagnetic induction heating, the human waste stored in the drying pot 41 is heated by the drying pot 41 and the heat storage unit 50, and the temperature rises. When the temperature of the human waste rises in this way, the stored human waste is eventually heated to a temperature at which it boils, and the water, which is a major component of the human waste, becomes water vapor and evaporates from its surface.

<< Reheating by Reheating Heater 134 >>
>

As described above, since the heater control circuit 203 starts supplying power to the reheater 134, the tip of each bar-shaped reheater 134 generates heat at a high temperature. This reheater 13
When 4 generates heat, the internal space of the flow guide hole 132 formed in the heat resistant material 131 shown in FIG. 15 is heated at a high temperature. For this reason, the air flowing in the internal space of the flow guide hole 132 is heated by contacting the heated end of the reheater 134, and flows upward at a high temperature. As described above, the reheating heater 134 heats the air flowing through the flow guide hole 132 by using the catalyst body 140 installed above.
This is because the air is brought into contact with air to cause oxidation and reduction. This is because unless the catalyst contained in the catalyst body 140 is maintained at a high temperature, the redox function is not exhibited.

<< Cooling of Cooling Box 129 >>

Then, the central processing circuit 191 outputs a control signal to the motor control circuit 201 at the same time, and the motor control circuit 201 operates the cooling fans 135 and 136 to cool the cooling box 129. When the cooling fan 135 operates, air is sucked in the direction B in FIGS. 14 and 15, and external cold air flows into the space inside the cooling box 129. When the cooling fan 136 operates, air is discharged in the direction C in FIGS. 14 and 15, and hot air is discharged from the space in the cooling box 129 to the outside. The air in the space inside the cooling box 129 is circulated by these cooling fans 135 and 136 because the temperature of the cooling box 129 rises due to the heat generated by the reheating heater 134. The tip of the reheater 134 generates heat at a high temperature, and the reheater 134 on the back side of the heat-resistant material 131.
This is because the temperature of the electrode side, which is the base portion, also becomes high. If the electrode side is not cooled, the reheater 134 will be consumed quickly and the electrode will be melted.

<< Release of Air in Drying Kettle 41 by Exhaust Portion 25 >>

The central processing circuit 191 outputs a control signal to the motor control circuit 201,
1 starts the operation of a motor (not shown) housed inside the blower 145. Then, the blower 145 sucks air from the intake pipe 146 opened on the side surface and discharges the air in the direction of the eject pipe 147, and the discharged air flows through the internal space of the eject pipe 147 and flows from the open end of FIGS. Are ejected in the direction E in FIG. When air flows through the eject pipe 147, the core pipe 14 provided in the middle of the
8, the air passes at a high speed, and the outlet 1
Negative pressure is generated around 49. For this reason,
The air inside the core pipe 148 is sucked from the discharge port 149 by the negative pressure, and the air is discharged in the F direction in FIG. Since the core pipe 148 communicates with the internal space of the catalyst box 139 as shown in FIG. 15, the air inside the catalyst box 139 is discharged by discharging air in the F direction. The lower part of the catalyst box 139 is the flow guide hole 1
32, the connecting pipe 130, and the exhaust pipe 56 communicate with the inside of the drying kettle 41.
The air inside 1 is exhaust pipe 56, connecting pipe 130,
The suction hole 132, the catalyst box 139, the exhaust pipe 141, and the core pipe 148 are sucked in this order. The aforementioned drying pot 41
The steam and air of the human waste generated by heating the air is mixed with the air from the blower 145 inside the eject pipe 147 and diffused into the outside air from the open end of the eject pipe 147.

Although the air in the drying pot 41 is sucked in the direction of the eject pipe 147, the same amount of air as the discharged air must be newly introduced into the drying pot 41. When the air flows through the eject pipe 147, the air flows into the intake 151 of the air pipe 150 located at the end of the eject pipe 147, and a part of the discharged air flows through the air pipe 150. This air pipe 1
After flowing through the inside of 50, the air passes through the switching valve 161 and the air supply pipe 162, and then flows into the drying pot 41 through the air hole 54 opened on the upper surface of the holding plate 35. This fresh air promotes the oxidation of the human waste stored in the drying pot 41.

In such an air flow, the flow guide hole 1
When the air flows through the inside of the heater 32, the air comes into contact with the tip of the reheater 134 that is generating heat, is heated, reaches a high temperature, and flows toward the catalyst 140. The water vapor and air evaporated from the drying pot 41 contain elements that cause malodor such as ammonia and bromine, and cannot be released to the outside air as it is. However, when the air from the drying pot 41 passes through the catalyst 140, these malodorous elements come into contact with the catalyst such as platinum and rhodium stored in the catalyst 140, and the malodorous elements are oxidized and reduced to an odorless state. It is transformed and flows into the upper space of the catalyst box 139.

<< Rotating Motion of Stirring Unit 28 >>

The central processing circuit 191 outputs a control signal to the motor control circuit 201,
The operation of the motor 108 is started by the
In step 08, the stirring unit 28 is rotated. Motor 10
When power is supplied to the motor 8, the rotational output of the motor 108 is reduced in speed via the gear box 109, and the output shaft 110 at the upper end is rotated at a low speed. Then, the pulley 113 fixed to the output shaft 110 also rotates at the same time, as shown in FIGS. 5 and 7, the pulley 85 is driven via the belt 114, and the drive fixed to the center thereof by the rotation of the pulley 85. The shaft 66 is rotated in the horizontal direction (the pulley 85 and the drive shaft 66 are
Since the key 87 is engaged as shown in FIG.
It rotates synchronously without any horizontal slippage.) As shown in FIGS. 10 and 11, the drive shaft 66 is rotatably held on its upper and lower sides by the outer barrel 66 by bearings 74 and 81, so that the drive shaft 66 rotates smoothly in the horizontal direction. In this way, the belt 114
When the pulley 85 is driven through the pulley 8, the rotational force is transmitted to the drive shaft 66 via the key 87 and the pulley 8 is driven.
5 and the drive shaft 66 rotate simultaneously in the same direction.

The lower part of the drive shaft 66 is shown in FIGS.
Since the agitating unit 28 is suspended as shown by the arrow, the entire agitating unit 28 rotates in the horizontal direction together with the drive shaft 66. In this rotation operation, a connecting plate 95 is connected to a connecting plate 68 fixed to the lower end of the drive shaft 66, and the connecting plate 95 is formed of a hanging pipe 97, an oblique pipe 98, and a suction pipe 99. Since these pipes are suspended, these pipes rotate in synchronization with the drive shaft 66 inside the drying pot 41. In addition, as shown in FIGS.
1 and the suction pipe 99 is connected to the drive shaft 6.
It rotates while drawing a circular locus inside the drying pot 41 with the rotation center 6 as the center of rotation. The lower end opening of the suction pipe 99 is rotated with an interval that does not contact the bottom surface of the drying pot 41.

When the suction pipe 99 rotates, the triangular plates 100 and 101, the stirring plate 104, and the skirt plate 105 connected to the side surface of the suction pipe 99 are also simultaneously dried.
A circular rotation will occur within 1. This stirring plate 10
4. In the rotation of the skirt plate 105, as shown in FIG.
The stirring plate 104 and the skirt plate 105 rotate in the form while dividing the space of the drying pot 41 into two, and the stirring plate 1
Both end portions of the skirt plate 105 rotate so as not to contact the inner wall of the drying pot 41 at a small interval, and the lower end of the skirt plate 105 rotates so as not to contact the bottom of the drying pot 41 at a small interval. For this reason, as shown in FIG. 6, the stirring plate 104 and the skirt plate 105 rotate so as to stir the human waste inside the drying pot 41, and at the same time, rotate while pressing the heat storage body 50 housed in the drying pot 41. Will be moved.

<< Stirring of Human Waste by Thermal Storage 50 >>

As described above, when the motor 108 is operated, the entire stirring section 28 is rotated by the rotation force of the motor 108, and the regenerator 50 charged in the drying pot 41 is stirred by the stirring plate 104 and the skirt plate 105. It will roll inside. Drying pot 4 with stirring plate 104 and skirt plate 105
The urine stored in the drying pot 41 is stirred by the stirring plate 10 so that the heat stored in the drying pot 41 is rolled at the same time as the urine stored in the container 1 is stirred.
4. Stirring is performed by the skirt plate 105 and the heat storage body 50, and the sewage is stirred so that the temperature of the whole sewage becomes uniform. In the agitation and rolling operations, the excrement adheres to the surface of each heat storage element 50 sequentially, and the heat generated by the heat storage element 50 is transmitted to the excrement, respectively, and performs an auxiliary action of raising the temperature of the excrement. . In this way, while the excrement is being stirred by the regenerator 50, the temperature at which the exotherm is generated is transmitted, and the temperature of the entire excrement is increased.

[0178] At the center of the bottom of the drying pot 41, as shown in the sectional view of Fig. 7, a projection 43 whose center is raised is formed. Since the projections 43 are located at the center of the bottom of the drying pot 41, when the plurality of heat storage elements 50 are rolling inside the drying pot 41, the heat storage elements 50 slide down the slopes of the projections 43. In addition, the heat storage body 50 rolls around the drying pot 41 without gathering at the center of the drying pot 41. For this reason,
Even if a plurality of heat storage bodies 50 roll, each heat storage body 5
0 does not collect in the shape of a dumpling at the center of the drying pot 41, but always rolls near the bottom around the drying pot 41, so that the human waste can be surely stirred.

<End of Evaporation / Drying of Human Waste by Drying Kettle 41>

As described above, the stirring unit 28 is rotated while the drying pot 41 and the heat storage unit 50 are heated by the high-frequency coil 118, so that the human waste stored in the drying pot 41 continues to boil, and the human waste constituting the human waste becomes large. Moisture, a component of the part, will continue to evaporate. If this evaporating operation is continued,
All of the human waste stored in the drying pot 41 is evaporated. If all the human waste in the drying pot 41 evaporates, it is no longer necessary to continuously heat the drying pot 41 and the heat storage unit 50 with the high-frequency coil 118, and the evaporating / drying process must be completed. The end of this processing is performed by the temperature sensor 180
Can be detected.

When all of the human waste stored in the drying pot 41 is dried, since the human waste has been evaporated until then, the drying pot 4
Although the temperature of 1 was maintained near the boiling point, the temperature of the drying pot 41 suddenly rises because there is no human waste absorbing heat. The temperature of the drying pot 41 is determined by the temperature sensor 1
If the temperature outside the drying pot 41 rises rapidly due to the evaporation of the human waste, the temperature change is detected by the temperature sensor 180. A temperature change detection signal from the temperature sensor 180 is sent to a temperature discrimination circuit 196.
The temperature discrimination circuit 196 discriminates that all the human waste in the drying pot 41 has been evaporated. Then, the determination signal from the temperature determination circuit 196 is output to the central processing circuit 191. The central processing circuit 191 stops the evaporation / drying processing and instructs the next cleaning processing.

<< Stopping Heating of Drying Kettle 41 >>

The central processing circuit 191 outputs a signal for stopping the operation to the heater control circuit 203, whereby the heater control circuit 203 stops supplying power to the reheating heater 134 and the high frequency generation circuit 204. For this reason, the reheating heater 134 stops generating heat, and the high-frequency generation circuit 2
At 04, the supply of high-frequency power to the high-frequency coil 118 is stopped, and the heating of the drying oven 41 and the heat storage unit 50 is stopped. The reheater 134 and the high-frequency coil 118
Even if the heating is stopped, the central processing circuit 191 maintains the control signal to the motor control circuit 201, and the motor 108 and the blower 145 continue their operation as before.

<Start of cleaning process>

Next, the central processing circuit 191 starts the cleaning process according to the procedure of the program stored in advance. As described above, when the human waste is evaporated and dried in the drying pot 41, the water, which is a major component, evaporates, but the organic and inorganic substances contained in the human waste remain as dust. When such dust accumulates in the drying pot 41, the dust adheres to the inner wall and bottom of the drying pot 41 and remains on the drying pot 41. Depending on long-term use, the stirring plate 104, the skirt plate 105, and the heat storage body 50 may remain in the drying pot 41. It becomes impossible to rotate, and finally, the function of the temporary toilet 11 is not fulfilled. For this reason, when the process of evaporating and drying the human waste is completed, a cleaning process must be performed next to remove dust remaining in the drying pot 41.

In this cleaning operation, the central processing circuit 191 outputs a control signal to the motor control circuit 201 to start the operation of the motor 159, and at the same time, outputs a control signal to the on-off valve control circuit 202 to open and close the motor. The valve 171 is opened. When the motor 159 is operated, the suction device 15
7 starts to rotate, and the collection box 15
2 to suck the air inside and discharge it toward the discharge pipe 158,
It discharges in G direction in FIG. Then, the inside of the collection box 152 becomes negative pressure through the filter 156 by the suction of the air by the fan 174, and the air is sucked into the collection box 152 from the introduction pipe 154.

[0187] Therefore, the air in the drying pot 41 is sucked from the lower end opening of the suction pipe 99, flows through the suction pipe 99, the inclined pipe 98, and the hanging pipe 97, and then opens at the center of the drive shaft 66. It passes through the ventilation hole 67, passes through the on-off valve 171, the dust suction pipe 172, and the introduction pipe 154, and flows into the garbage bag 155. The air that has passed through the garbage bag 155 flows into the internal space of the collection box 152, passes through the filter 156, and then passes through the suction device 157, the discharge pipe 158, the air supply pipe 175, the check valve 176, and the air supply pipe 177. From the discharge pipe 142 into the upper space of the catalyst box 139. The air in the upper space of the catalyst box 139 is sucked from the discharge port 149 by the ejector effect by the exhaust unit 25 as described above, and
The air is released from the opening 47 to the outside air. In this way, a series of air flow paths from the suction pipe 99 to the discharge pipe 142 are formed.

When the air is sucked from the lower end opening of the suction pipe 99 and flows in the direction of the collection box 152, the lower end opening of the suction pipe 99 is close to the bottom of the drying pot 41. Dust remaining due to non-evaporable organic and inorganic substances remaining at the bottom of the suction pipe 99 is sucked together with air from the lower end opening of the suction pipe 99. Then, the dust sucked together with the air is caused to flow into the garbage bag 155 according to the above-described route. In the garbage bag 155, the air passes through the film surface, but the dust is caught by the fine mesh of the film surface. You. For this reason, the dust bag 155 separates dust from the air that has flowed in, and acts to pass only clean air into the internal space of the collection box 152. The dust remaining in the drying pot 41 is captured by the dust bag 155. Is done.

At this time, the motor 108 continues to operate after the evaporating / drying process, and the stirring unit 2 is driven via the pulley 113, the belt 114, and the pulley 85.
The whole 8 rotates in a circular locus like a miso rubbing motion in the drying pot 41. For this reason, the lower end opening of the suction pipe 99 rotates circularly at the bottom of the drying pot 41, and sucks up the dust accumulated at the bottom of the drying pot 41 uniformly. Further, when the stirring unit 28 rotates, the stirring plate 10 is rotated.
4. Since the skirt plate 105 rotates at the same time and the heat storage body 50 is rolled at the bottom of the drying pot 41, the heat storage body 50
As a result, the dust accumulated on the bottom of the drying oven 41 is peeled off and finely crushed, and the dust accumulated on the bottom of the drying oven 41 is peeled and finely crushed so as to be easily sucked together with air.

In this manner, the dust sucked up from the lower end opening of the suction pipe 99 is captured by the garbage bag 155,
The clean air that has passed through the membrane surface of the garbage bag 155 passes through the filter 156 and is discharged to the upper opening of the catalyst box 139 through the above-described path. In this flow of air, the valve opens inside the check valve 176 and the air supply pipe 1
Since the flow of air to the air supply pipe 177 is allowed from 75, air flows smoothly in this flow direction. Then, the clean air discharged into the upper space of the catalyst box 139 is sucked in the air at the discharge port 149 (the blower 145 continues to operate following the heating / drying process and continues to operate. ), Flows in the order of the exhaust pipe 141 and the core pipe 148, is mixed with the air flowing through the eject pipe 147, and is discharged from the open end of the eject pipe 147 to the outside air.

<Stop of cleaning process>

As described above, when the cleaning process by suctioning the dust accumulated in the drying pot 41 is performed for a predetermined time, the dust stored in the bottom of the drying pot 41 becomes dusty. It is captured by the bag 155 and the cleaning process is completed. Then, the temporary toilet 11 must automatically stop the cleaning process and return to the initial state. This is because the user must use the temporary toilet 11 next and wait for the user to excrete the toilet 16.

When the cleaning process is stopped, if a predetermined time has elapsed since the start of the cleaning process, the central processing circuit 191 makes a self-determination based on a program stored in the central processing circuit 191 in advance. Outputs stop signal.
Therefore, the central processing circuit 191 is connected to the motor control circuit 20.
1 to output a control signal, stop the operation of the motor 159, stop the suction of air by the fan 174, and stop the suction of air from the drying pot 41 by the suction pipe 99. At the same time, the central processing circuit 191
2 also outputs a control signal, and the ventilation hole 67 and the dust suction pipe 17 are output.
2 is closed. Thus, the air flow path from the lower end opening of the suction pipe 99 to the distal end opening of the discharge pipe 142 is closed, the air and dust do not flow, and the cleaning process is stopped.

The above-described series of processing operations is continuously performed even if the power switch 192 is turned off halfway. This is because once the excrement is introduced into the drying pot 41, one processing cycle must be completed and all the excrement in the drying pot 41 must be evaporated unless a part of the apparatus is broken down. . If the power switch 192 is turned off due to carelessness of a worker during the processing and the <evaporation / drying processing> is stopped, the human waste remains in the drying pot 41 as it is, and when the next use, This is inconvenient.

<Do you want to start the next processing cycle?>

In this way, if the <cleaning process> and the <cleaning process are stopped after the <evaporation / drying process>, the operation of the temporary toilet 11 is stopped or the next processing cycle is performed. Is determined, and whether the cleaning operation of the catalyst 140 is to be performed. The operation of the temporary toilet 11 is stopped based on whether the power switch 192 is turned off. If the processing is proceeding up to this point and the power switch 192 is turned off, the central processing circuit 191 stops all operations of the temporary toilet 11. However, even if the processing cycle is in progress, the power switch 19
If No. 2 is turned on, the processing cycle returns to <Evaporation / drying processing> described above, and performs the action of heating and evaporating the excrement again. If the central processing circuit 191 determines by itself that cleaning of the catalyst body 140 is necessary, the operation proceeds to the cleaning processing operation.

<Process of Evaporation and Drying of Human Waste Again>

When the condition that the above-mentioned <Stop of cleaning processing> is completed and the power switch 192 is turned on, and the user who next uses the temporary toilet 11 presses the processing switch 183 to turn on, the central processing is performed. The circuit 191 again performs
Evaporation / Drying Process> is started, and the next processing cycle is continued. This processing is performed by the central processing circuit 1 in the same manner as described above.
From 91, the on-off valve control circuit 202 and the heater control circuit 20
A control signal is output to each of them, and a predetermined amount of human waste is injected into the drying pot 41 in the same manner as described above, and the processing of evaporation and drying of the human waste is performed in the drying pot 41. In the same manner as described above, the cycle of this processing is the cycle of <evaporation / drying processing>, <cleaning processing>, <stopping of cleaning processing>, <judgment of stopping processing cycle>. It is repeated continuously unless 192 is turned off.

<Cleaning Process of Catalyst 140>

[0200] In this way, the urine is excreted in the toilet bowl 16,
When the cycle of the process of evaporating and drying human waste is repeated in the drying pot 41, air mixed with dust flows in the catalyst 140 for removing odor. Then, the dust adheres to the catalyst particles and the honeycomb structure constituting the catalyst body 140, which causes a hindrance to air flow. For this reason, a process of cleaning and removing dust adhering to the catalyst body 140 during the above-described processing cycles of <evaporation / drying processing>, <cleaning processing>, and <stopping of cleaning processing> must be performed. No. The operation of the cleaning process of the catalyst body 140 is not performed every one processing cycle, but is performed.
The cleaning is performed at a time when dust adheres to the catalyst body 140 and needs to be cleaned. This operation is based on the processing cycle described above.
For example, it is automatically started when the number of times such as 50 or 100 is performed.

<< Count of Processing Cycle >>

As described above, the central processing circuit 191 outputs a control signal to each of the motor control circuit 201, the on-off valve control circuit 202, and the heater control circuit 203 to perform the operation of one processing cycle. Arithmetic circuit 19
1 outputs to the counting circuit 198 a signal indicating that one processing cycle has started. The count circuit 198 counts the number of times this processing cycle has been performed.
A preset number (for example, 50 times, 100 times, etc.)
The count is stored until it reaches. Central processing circuit 1
When the signal of the number of processing cycles from 91 reaches a preset number, the counting circuit 198 starts the central processing circuit 1
A signal for starting the cleaning of the catalyst body 140 is output to 91.
After the counting signal is transmitted to the central processing circuit 191, the cleaning process is started.

<< Switching of Human Waste Processing Apparatus 15 >>

When cleaning of the catalyst 140 is to be started, the central processing circuit 191 sends control signals to the pump control circuit 200, the motor control circuit 201, and the on-off valve control circuit 202, respectively, to check the state of the equipment for cleaning processing. Switch to. First, the pump 1 is controlled by the pump control circuit 200.
64 operates to draw the cleaning water stored in the water tank 186 and flow it to the injection pipe 126. The on-off valve control circuit 202 closes the communication between the exhaust pipe 56 and the connection pipe 130 by closing the on-off valve 124. At the same time, the on-off valve control circuit 202 switches the switching valve 161 to connect the air pipe 150 and the air supply pipe 125, and directs the flow of air toward the air supply pipe 125. Then, the motor control circuit 201 stops the operations of the motors 108 and 159 and the cooling fans 135 and 136, and the heater control circuit 203 stops the supply of electric power to the reheater 134 and the high frequency generation circuit 204. In this way, the human waste processing device 15 is temporarily suspended in its human waste processing function,
Only the process for cleaning the catalyst body 140 is switched. However, the motor control circuit 201 operates only the blower 145, and the eject pipe 147 by the blower 145.
The air supply in the direction is left to continue.

<< Injection and Cleaning of Washing Water >>

As described above, when the cleaning water is sent from the pump 164 to the injection pipe 126, the cleaning water is discharged from the end of the injection pipe 126 into the internal space of the catalyst box 139, and is sprayed on the upper portion of the catalyst body 140. You. This catalyst body 14
Since 0 only accumulates the particulate catalyst, the washing water flows down through between the particles. Then, it flows down to the closed on-off valve 124 and is stored inside the flow guide hole 132. When the washing water is sequentially stored, the liquid level rises, and finally the inside of the catalyst box 139 is filled with the washing water. If the level of the washing water rises and reaches a position slightly higher than the upper surface of the catalyst body 140,
Since it is not necessary to fill the inner space of the catalyst box 139 with the washing water any more, the washing water is supplied to the overflow pipe 127.
Will flow out of the opening. The washing water flows down the overflow pipe 127 and is injected into the drying pot 41 from the lower end opening thereof, and when the human waste is later put into the drying pot 41, the washing water is also evaporated at the same time.

The pump 164 is operated for a preset time.
Is activated, the flushing water flows into the overflow pipe 1
Central processing circuit 191 determines that it has been filled to the height of 27, and instructs pump control circuit 200 to stop the operation. As a result, the operation of the pump 164 stops, and after that, the washing water in the water tank 186 is removed from the injection pipe 12.
Not sent to 6. Thus, the flow hole 132 and the catalyst box 13
9 is filled with the washing water, and the entire catalyst body 140 is immersed in the washing water. Since the switching valve 161 is switched, the air flowing through the eject pipe 147 flows in from the inlet 151 of the air pipe 150, and the air pipe 150 and the switching valve 16 are switched.
1. Flow in the order of the air supply pipe 125, and the connecting pipe 130
Flows into the interior. This inflowing air is connected to the connecting pipe 1
It rises above 30 and the flow guide hole 132 and the catalyst box 1
The cleaning water filled inside 39 rises as bubbles and penetrates through the surface of the catalyst particles housed inside the catalyst body 140. When the air that has become bubbles comes into contact with the catalyst particles in the catalyst body 140, the air is stirred by the washing water, so that the dust adhered to the surface of each catalyst particle is removed, and the dust is removed by the washing water. Washed off. By continuing this operation for a predetermined time, the catalyst 140
Are cleaned.

<< Return to Normal Cycle >>

As described above, if bubbles are made to flow in the filled washing water to remove the dust adhering to the surfaces of the catalyst particles and to clean them, after a predetermined time has passed, the central processing circuit 1
The self-determination unit 91 determines that the cleaning process has been completed, and returns to the normal human waste processing cycle. In this return operation, the central processing circuit 191 sends the motor control circuit 2
01, open / close valve control circuit 202, heater control circuit 203
, Respectively, to return to the original operation state. At the same time, the central processing circuit 191
Then, a reset signal is output to the counter 8 to return the number of times of processing of the excrement counted by the counting circuit 198 to "0", and the number of times of processing the excrement is again measured.

First, the motor control circuit 201 restarts the operation of the motor 108 and the cooling fans 135 and 136,
The stirring unit 28 is rotated inside the drying pot 41, and the inside of the cooling box 129 is cooled by the cooling fans 135 and 136. In the on-off valve control circuit 202, the on-off valve 124 is opened to connect the connecting pipe 130 and the exhaust pipe 56, and the washing water filled in the flow guide hole 132 and the inside of the catalyst box 139 is caused to flow downward. Into the drying pot 41.
The washing water stored in the drying pot 41 is evaporated at the same time as the drying and evaporating process of the excrement. Further, the switching valve 161 is switched, the air pipe 150 is communicated with the air supply pipe 162, and the air is supplied to the inside of the drying pot 41 for oxidation, not in the direction of the connection pipe 130. Then, the heater control circuit 203 supplies power to the reheating heater 134 and the high frequency generation circuit 204 to generate heat, and supplies high frequency to the high frequency coil 118 by the high frequency generation circuit 204 to heat the drying pot 41. Then, it waits so that the human waste can be processed immediately.

<Return to standby state>

Thus, the processing cycle of human waste is as follows:
<Evaporation and drying process>, <Cleaning process>, <Cleaning process stop>, <Judgment of process cycle stop> are repeated,
If this cycle is continued a predetermined number of times, the <processing for cleaning the catalyst body 140> will be performed halfway. When the <cleaning process of the catalyst body 140> is completed, the process returns to the processing cycle of the human waste on the previous day, but when there is no user using the temporary toilet 11 (for example, at night or on holidays). And when there are no more users), the condition is that the power switch 192 is turned on after the operation of <Cleaning process stop>, the process does not shift to the normal process cycle, and the temporary toilet 11 Move to the standby state. That is, when the processing switch 183 is not turned on and the state of <cleaning processing is stopped> is reached, the central processing circuit 191 does not shift to the cycle of processing human waste and stops the entire temporary toilet 11. Let me wait. This standby state is the same as the start of the process at the beginning.

For this reason, the central processing circuit 191 outputs a control signal to the motor control circuit 201 to stop the operation of the motor 108. Then, the stirring unit 28 that has been rotated in the drying pot 41 is stopped by the driving force of the motor 108, and the rotation of the stirring plate 104, the skirt plate 105, and the heat storage unit 50 is stopped (the heater control circuit 203 sets the < Since the supply of power to the reheater 134 and the high-frequency generation circuit 204 is stopped at the time of the cleaning process, the reheater 134 does not generate heat.
Since no high-frequency power is supplied to 18, the drying pot 41 is not heated.) This standby state continues until the user excretes human waste to the toilet bowl 16 and the user turns on the processing switch 183. When the power switch 192 is turned off in this standby state, the temporary toilet 11 stops all of its functions.

<Stopping the operation of the temporary toilet 11>

The operation of the temporary toilet 11 can be stopped by turning off the power switch 192. For example, there is a case where there is no need to process night soil at a temporary setting site or a venue for entertainment, or the temporary toilet 11 is stored in a warehouse from the installation location. In such a case, the manager or the worker manually turns off the power switch 192, so that the temporary toilet 11
The whole operation stops. However, as described above, even if the power switch 192 is turned off while a processing cycle such as <evaporation / drying processing> or <cleaning processing> continues, the processing in that cycle continues and is performed once. The operation does not stop until the processing cycle is completed. When the processing cycle ends, the function of the temporary toilet 11 stops.

<Flowchart showing processing cycle>

[0222]

As described above, according to the first aspect of the present invention, when the cleaning water is injected into the deodorizing means after the on-off valve is closed, the cleaning water comes into direct contact with the catalyst. The attached dust can be cleaned. For this reason, dust that cannot be removed only by blowing air on the catalyst body can be reliably removed, and the function of the catalyst body can be restored. In addition, the clean water after the cleaning of the catalyst body falls into the container by opening the on-off valve, and can be evaporated when the container is next heated, so that the container and the deodorizing means are not disassembled. , Can be automatically cleaned.

According to the second aspect of the present invention, since the blowing means for sending air is connected between the deodorizing means and the on-off valve, the blowing means is provided after clean water is injected into the internal space of the deodorizing means. When air is sent, air flows between the clean water in contact with the catalyst. Since this air flows in a gap between the catalyst and the clean water in a bubble-like manner, the air acts to scrape the surface of the catalyst and can remove dust adhering to the surface of the catalyst. For this reason, even the dust firmly adhering to the surface of the catalyst body can be reliably removed.

According to the invention of claim 3 of the present application, the reheating means is connected to the lower part of the deodorizing means, and the clean water injected into the deodorizing means can fill the internal space of the deodorizing means and the reheating means. it can. For this reason, dust adhering to the inner wall of the reheating means can be simultaneously cleaned with clean water. The cleaning of the reheating means could not be performed without disassembling the mechanism, but can be performed at the same time as the cleaning of the deodorizing means, so that work such as disassembly becomes unnecessary and long-term use becomes possible.

According to the invention of claim 4 of the present application, the upper end of the drainage means is communicated with the internal space of the deodorizing means, and the upper end of the drainage means is lower than the injection means and higher than the upper surface of the catalyst. Is also set at the upper position. For this reason, even if the clean water is injected from the injection means, the clean water overflowing by the drain means flows out, so that the height of the water surface can be set at a fixed position. Therefore, the cleaning operation can be performed with a sufficient amount of clean water to make sure that the entire catalyst body is brought into contact with the clean water without injecting a large amount of clean water by mistake and overflowing into the deodorizing means. . Further, since the clean water overflowing from the drainage means is injected into the container, it is heated and evaporated at the time of the next processing of human waste, so that it can be automatically processed.

According to the invention of claim 5 of the present application, an exhaust means for sucking and discharging steam and air during a normal processing cycle is connected to the upper part of the deodorizing means. A part of the discharged air is supplied to an air supply means. Therefore, air for cleaning the catalyst body can be supplied by the operation of the exhaust means, and the mechanism for exhaust can be diverted as it is to the means for pressure-feeding the air in normal processing. There is a feature that the mechanism is simplified because the same exhaust means is shared.

According to the invention of claim 6 of the present application, an exhaust means for sucking and discharging steam and air during a normal processing cycle is connected to the upper part of the deodorizing means. It is possible to select whether to supply a part of the discharged air to the container or the deodorizing means by the switching valve. For this reason, in the normal processing cycle of human waste, air can be supplied to the container and used for oxidation of the human waste,
In the process of cleaning the catalyst, air can be supplied to the deodorizing means and used for removing dust. The air discharged from the exhaust means can be made to flow for a plurality of uses, and does not require a dedicated air pumping means.
